CUSHIOLTUFTING AND RlVET-SETTNG WACl-IINE.

Application led March 5, 1925.` Serial No. 13.04A.

'l'his invention relates to a machine for use in tufting cushions by .setting tufting mem* bers of the rivet type therein7 and also to a method for performing a tufting operation.

The invention includes a vertically movable anvil member arranged to be lifted into engagement with the underside of a cushion and to be loclred in raised position to provide an anvil surfer with which rivet setting mechanism is arranged tov cooperate in setting a tu'fting member in place in the cushion.

Another feature 'of the invention resides in the provision of means automatically operable following the operation of the rivet setting mechanism for unlocking ythe anvil member to permit the anvil member to dcscend to a. lowered position to provide for changing the position of the work.

T he anvil elevating means and thc rivet setting mechanism are preferably arranged to be operated through the manipulation of a pair of foot treadles mounted adjacent each other for separate and successive operation to raise the anvil member to operative position and then to actuate the rivet setting mechanism. l

.lhe locking means for the anvil member preferably consists of springpressed bolt which automatically engages with a stationary part when the anvil member has reached its elevated position. Means operating automatically upon the retraction of the rivet .son 1g mechanism retracts the boltl from .its locking pos-tion and releases the anvil member to descend to its lowered posi tion.

Another feature of the invention resides in the use of sliock-absorbing means for cui-ihioning the descent ofthe anvil member and irireventing the production of noise.

@their features of the invention will be hereinafter referreril to.

Y `Referring to the drawings for a more de-` tailed description of the invention, in Figure 1 there is shown a tufting machine embodying the invention and including a base member l0 from which a vertical standard or frame member 11 projects upwardly to support a head member-.12 on which rivet feeding mechanism 13 and rivet setting meehanism 11i are carried.

Projecting forwardly from the upper extremity of the standard 1l is a table or shelf member 15 on which the work may be received as a preliminary to the carryingout of a tufting operation thereon. The

.shelf 15 is supported on bracket members 16 which are bolted directly tothe standard 11 and the base portion of the head member CAD ting` and forming` head member 23 against Which the tutting rivet is forced for an upsetting operation thereon.

The vertically movable anvil member 22 is koperated through an arm 23 which passes through a slot formed for the purpose in the rear ivall of the guide member 18 and pivotally engages at 253'; with the anvil member 22 passing into slot 25 formed inthe anvil member 22 for the purpose. The other end of the arm 23 is pivotcd at 26 to a lever 27 equipped with a toot treadle 28 at its outer extremity and pivoted at a mid point 29 to the toi-'warn standard or frame piece 20. Through the arrangement described7 depression or' the toot treadle 23 acts to elevate the anvil member 22,:rom a` lowered to the elevated position shown in Figures l and 2 of the drawing.

ln order to lock the anvil member in its raised position, a spring-pressed bolt 30 is Vslid-.ably mounted lateral movement in a.

slideivay 3l formed in the anvil member for the purpose. A recess 32 extending longitudinally in the side oi the anvil member adjacent the slideivay 3l terms a seat Jfor a spring 33 which engages the adjacent end o" the bolt 30 and causes the bolt to move into an opening Sein the vtrame member 'i8 to t-hereby loclr the anvil member in fixed position Within the slidevvay In order to unlatch or unlock the anvil member 22 when it is necessary to cause the anvil to descend to provide for changing ci the position of the cushion 35 or other Work, a latch operatingbar is mounted to slide in a vertically ez-:tending groove 3i' formed in the anvil member 22 and to engage a bolt operating meml er 38 mounted tor partial rotation on a pin 39 extending into the bolt 30 and having slidingv movement in a notch 40 in the We 1 oLt the linvii member 22. The spring has a section 33 arranged to engage the member 33 and normally hold the same. in the position shown in Figure 5 of the drawing. rllhe bolt ope 'ating member 38 is mounted to slide and rock Within a notch or recess ll-l formed in the forward tace of the anvil member 22. The bolt operating` member is provided with a tooth 4t2 for engagement byr a cam member 4-3 'formed in the. vertically movable rod 36. y

With the construction described, the open ation of the latch operating` mechanism takes place `itolloivs: Upon a descending movement of the rod which accompanies the operatingv movement of the rivet set-ting device l-l, the cam member 43 on the slide bar 36 engages the tooth 42 on the latch operating` member 38 and partially rotates the member 38 in its seat thereby permitting the cam member 43 to pass downwardly past the position of the member 38 Without operating' the same other than to produce the yielding rotative movement referred to.

'Upon the return or upward movement or member ll.

the slide bar 36 which accompanies the return or idle stroke of the rivet setting device ills, the upper or cam tace of the cam member engages the lcvver surface of t-he tooth l2 and Jiorces the member 38 to the right as is shown in Figure of the drawing. lt will be seen that the translational movement ot' the member 38 Which is thus produced brings about the retraction ol the bolt 30 from its locking engagement with the recess 34. rEhe r1sultis that the anvil member 22 is released from its loclred position and is tree to descend in the guideway 2l.

ln order to cushion the descendinr movei ient ot the anvil niemiier 2', a shock-absorbing device 43 is connected at one end to the arm 23 and at the other end to a` Vtired point on the base member lO. lilith this arrangement a dash-pot eil'ect is produced which cushions the desc riding movement oi? the arm 23 and eliminates impact or clash ofthe descending` parts with accompanying noise.

'the Cesccndingimovement ot the arm 23 is facilitated through the use ol coilef spring tl attached at one end to the pivot pin and at the other to an arm used in the operation ot' the rivet setting' mechamsm.

The arm 45 pivoted at /iG on the stand ard ll and is provided at its YorvwartV end with a foot treadle 4:7. rl`he other cnd ot the arm or lever llis pivot-ally connected at .el-8 With a linlr Llf) connected to a roch arm pivotally mounted at 5l on the head member l2 of the machine. The roel; arm 50 has a link connection 52 with the joint '53 ot a pair ot tor'cgle arms which operate the rivet setting device lll. Another linl; 53T extends trom the roel; arm 50 and operates ratchet mechanism 5h forming part ot the rivet :t'c'cding mechanism i3. vin order to raise the trcadle member Lli to its elevated position iiolloivingr an operation ther-cot, a spring 57 connected at one end to the arm 45 is attached at its other end to a hcclrh on the forward face ot' the standard trame An adjustable stop member is provided torlimitiug' the iiipivard strolrc of the arm 1i-,5.

In order to adjust the precise position ot the anvil head member23 in its raised position the member is provided with a screwthreaded stem portion 60 having' ihrcaded engagement with a recessI (3l eftenflir-- 'f "'H- the end of the anvil member 22 as is e arf! shown in Figures 2 and l of the drawing. A lock nut 62 is provided 'for holdingl the anvil head member in its adjusted position.

' In order to release the anvil. head menber for downward movement Whenever desired and independently of the operative movements of the machine as a Whole, manually operable releasing member G3 is provided which can be forced into engagement with the end of the bolt to press the same from locking engagement with the recess 34.' A spring,` 64; acts to move the releasing member 63 toits inoperative position.

The cushioning device d3 reierredto is shown in detail in Figure 1l of the drawing and consists of an outercylinder 65 which is provided with an eye 'member 6G for attachment to a lug 67 on the base l0. `Within the cylinder 65 a hollow plunger' 68 is mounted for slidingengag'einent therein. The inner end of the cylinder 68 is closed and provided with a relatively small port 69. 'The outer end oit" the hollow piston or plunger is provided with ports 7 0 adapted to Vbe covered or uncovered by longitudinal movement ot a cover cap 7l connected to the outer end of the cylinder by means of a pin 72. rlhe cover cap member 71 is attached to the arm 23 through a suitable connecting member 73.

ln the operation of the device as a whole a preformed cap or rivet head member 7a i.

laid in acorrespondingly shaped recess formed in the end oit the anvil head member 23. The cushion or other work is then placed inposition on the anvil head member 23 and the trcadle 28 is depressed under the toet ofthe operator. This action elevates the anvil member QQ and lifts the cushion 35 into engagement with the rivet setting mechanism le. When the anvil member 22 has reached the desired position of elevation,

f the spring-pressed bolt 30 snaps into the notch 34C and locks they anvil member in its roperative position. n

With the parts held in the operative position referred to, thev other toot treadle 41:7 is depressed to bring about the operation ot the f rivet setting,` mechanism lll through the train- `terr-ed to, the toot treadlee7 is release-ed whereupon it is lifted under the action oi: the spring 57 to its elevated position shown iny Figure l of the drawing. yThe slide bar 36 is pivoted to the lever 45 at 76 so that in the upward movement oi. the lever 45 the slide bar 36 is raised to thereby engage the bolt operating` member 38 to thereby remove the bolt from its locking position and permitA the descent of the anvil member 22 in the slideway 2l. It will thus be seen that. the release of the treadle 47 at the end oi'a rivet setting; operation automatically brings about the lowering of the anvil member 22 and permits the repositioning,` of the cushion 35 for the next succeeding,` rivet setting operation.
